Soul Finger is the debut album of the Bar-Kays, issued three months after the single of the same name. It was recorded by Tom Dowd and Chris Huston on Friday, June 23, 1967, at the Stax studio in Memphis. Though all but one member of the group were black (Ronnie Caldwell being the only white member), the album cover art, by Loring Eutemey, suggests an interracial pop music party feeling. The instrumental band, after being signed in early 1967, was tutored by Al Jackson, Jr. and the other members of Booker T. & the M.G.'s, which shows in the tightness of the rhythm section. That summer they also were selected by Otis Redding as his new backup band.

The cover shows an early example of a t-shirt displaying a logo. The artwork was credited to Loring Eutemey.
